| titleOfInvention | Preparation method of P-TOPCon photovoltaic solar cell structure |
| abstract | The invention discloses a preparation method of a P-type crystalline silicon TOPCon battery structure, which is characterized in that the battery structure is an Ag grid line + SiNx layer + N + Layer + local SiO x + Poly layer with Al layer + SiNx layer + Al layer on back 2 O 3 Layer + P + . In addition, the preparation method of the battery is double-sided texturing → single-sided oxidation → single-sided microcrystalline silicon → phosphorus doping&Annealing → front mask → removing unmasked area → cleaning → single-sided N + phosphorus diffusion → removing the mask area to form SiOx + Poly layer → passivation → laser grooving → silk screen printing + sintering. The invention discloses a novel P-TOPCon battery preparation method, namely a selective emitter process for doping polycrystalline silicon in a PERC front surface field, which can effectively improve open-circuit voltage VOC, reduce Rs and improve FF, and the selective polycrystalline silicon doping process can effectively reduce ISC loss, thereby improving efficiency. |
